Bioanalysis Young Investigator: Halil Tekin
No full text Supervisor’s supporting comments I am very pleased to nominate Halil Tekin for the Bioanalysis Young Investigator award. Halil has proven himself to be an excellent researcher, a very bright laboratory member and a strong leader since joining my laboratory. He has excelled at all of the skills required of a PhD candidate at MIT with his research focusing primarily on future advances in drug development, drug discovery and medicine with high-throughput drug toxicity screening. His efforts have focused on developing novel biomimetic tissue constructs by microengineering methods to further advance the applications of implantable tissues and drug toxicity screening devices. Halil has demonstrated an unprecedented ability not only to learn new material quickly, but more importantly to synthesize new information and ask the important questions needed to move science forward. I am constantly impressed with Halil’s ability, drive and determination in learning, and contributing to the research conducted in my laboratory. Halil’s unique combination of a strong electrical engineering background and his current knowledge and experience in tissue engineering has enabled him to look at fundamental challanges in a novel and insightful way, which resulted in very interesting publications. Halil is an exceptional PhD student conducting outstanding research in tissue engineering which can bring novel applications in human health care. Halil published a paper in a top journal in the field of microtechnology, Lab on a Chip, describing a new way of making cell aggregates and then retrieving them from the microwells in a controllable manner for further experimentation and analysis. He also published a paper in Langmuir, introducing a novel method to fabricate conformally coated thermo-responsive microgrooves to form stripe tissues and harvest them in a temperature-dependent manner. These responsive microstructures can be scalable into high-throughput systems and potentially be useful in tissue-engineering, stem cell research, drug toxicity screening and be integrated in bioanalytical devices. Currently, he is focusing on mimicking biological complexity in microtissues by utilizing dynamic microstructures. I am confident that by utilizing his unique expertise of stimuli-responsive materials, microfabrication techniques and cell biology Halil will continue to make outstanding contributions to this area. </jats:p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
